Eysenck linked Extraversion to activation of the Ascending Reticular Activation System (ARAS), an area of the brain which regulates sleep and arousal transitions. Eysenck proposed that extraversion was caused by variability in cortical arousal: "introverts are characterized by higher levels of activity than extraverts and so are chronically more cortically aroused than extraverts Eysenck’s Extraversion-Arousal Hypothesis states that under low stimulation conditions, introverts will be more highly aroused than extraverts; however, under high stimulation, introverts may become over- aroused, which will feedback within the ARAS and result in decreases in arousal. Alternatively, extraverts tend to show greater increases in arousal under high stimulation. Eysenck also studied the relationship between neuroticism and activation of the limbic system using classical emotional conditioning models. His theory focused more on anxiety as a disorder than a personality trait. Eysenck’s theory predicts that introverts are more likely to develop anxiety disorders because they show higher neuroticism and stronger emotional conditioning responses under high arousal. His theory was criticized because introverts often show the opposite pattern, weaker classical conditioning under high arousal, and some supporting data confounded personality traits with time of day. Be familiar with research supporting this theory (music preferences & performance) Behaviors- study done at MU extraverts will turn the music volume up when given chance o Perform better on standardized tests with louder vs. quieter music Salivation - if give people spicy/tart food, introverts salivate more, suggesting their body reacts with greater physiological arousal o Extraverts more likely to eat spicy food, have more sex partners, things that boost arousal Know biographical information about Hans Eysenck Eysenck was Professor of Psychology at the Institute of Psychiatry , King's College London , from 1955 to 1983. He was a major contributor to the modern scientific theory of personality and a brilliant teacher who helped found treatment for mental illnesses.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
